Resum
This journal is © The Royal Society of Chemistry. The molecule 4-mercaptophenyldiphenylphosphine (Sdp) has been synthesized for use as a linker to immobilize Pd nanoparticles onto the surface of magnetite nanoparticles. The high loading shown by Sdp was attributed to the presence of one only anchoring (S) atom. The treatment of the resulting nanoparticles after Pd deposition with an aqueous solution of hydrogen peroxide permitted the removal of a large fraction (70%) of Sdp. Aberration correcte...
